The total mass of the module was 15,264 kg with the majority of that (10,334 kg) in the descent stage.

Aquarius served as a refuge for the astronauts during their return to Earth orbit, while its batteries were used to recharge the vital re-entry batteries of the command module that brought the astronauts through the Earth's atmosphere and to a safe spashdown on April 17, 2005.

The LunarModule was the portion of the Apollo spacecraft that landed on the moon and returned to lunar orbit.

The conspiracists' insistence that it poses a special problem for the lunarmodule is evidence of their lack of education and experience with rocket science.

The active forms of stabilization are very important to the lunarmodule's design because there is no air to push against fins and realign the rocket if its axis points in a different direction than its flight path.

The lunarmodule had two stages, one used for the descent and another for the return to lunar orbit and rendezvous with the command module.

The mission of Apollo 10 was to conduct all phases of Apollo spacecraft operations except the actual lunar landing, including rendezvous and docking between the CSM and LM in lunar orbit and descent of the LM to within 50,000 feet of the moon's surface.

The fourth successful manned lunar landing, this was also the first of the Apollo J missions capable of a longer stay on the lunar surface and the first to carry the LRV.

Falcon rejoined the CSM on the latter's 50th lunar orbit and the particles and fields (PandF) subsatellite was released on the 74th orbit.

Grumman Apollo LM The Apollo LunarModule was the lander portion of the Apollo spacecraft built for the US Apollo program to achieve the transit from Moon orbit to the surface and back.

It consisted of two stages—the descent stage module and the ascent stage.

The Apollo LunarModule came into being because NASA chose to reach the moon via a lunar orbit rendezvous (LOR) instead of a direct ascent or Earth orbit rendezvous (EOR) (see Choosing a mission mode for more information on the available rendezvous types).

A lunarmodule test article was mounted in the spacecraft/launch vehicle adapter for mass loading purposes.

The most significant change was the replacement of the forward pressure and ablative hatches with the combined forward hatch, which was required for intravehicle transfer to the lunarmodule on later missions.

July: Seeing the Lunar Module(Site not responding. Last check: 2007-11-07)

Although the HST is a powerful instrument, and has no atmosphere to contend with, a lunarmodule at 376000 km is just too small an object at too great a distance.

Hubble has been aimed at the lunar crater Copernicus, and although the image was very detailed the theoretical limit of resolution is about 85 metres - not nearly small enough for the task.

This photograph was taken from the Apollo 17 Command Module, orbiting about 100 km above the lunar surface (about ¼ of the altitude of the International Space Station above the Earth), and is the remarkable climax of a sequence of progressively more detailed lunar surface images on the website "Exploring the Apollo Landing Sites".

Lunar orbit insertion was accomplished at 19:47:23 GMT on 12/10/72 placing the spacecraft into a lunar orbitof 170nm by 52.6 nm.

AT 14:35:00 GMT on 12/11/72, the Commander and LunarModule Pilot entered the LM to prepare for descent to the lunar surface.

Deorbit firing of the ascent stage was initiated at 06:31:14 GMT on 12/15/72 and lunar impact occurred 19 min 7 sec later approximately 0.7 nm from the planned target at latitude 19deg 56min North and longitude 30 degrees 32min East.

The lunarmodule landed two men (Commander Charles P. "Pete" Conrad and LM Pilot Alan L. Bean) on the surface of the moon in the vicinity of Surveyor 3, while the piloted (by CM pilot Richard F. Gordon Jr.) command module continued in orbit.

An Apollo lunar surface experiments package (ALSEP) was placed on the lunar surface, samples of the lunar terrain were acquired, and various photographs of 16-, 35-, and 70-mm film sizes were exposed from the lunar and command modules and by the astronauts during lunar surface activities.

The Command Module "Yankee Clipper" is on display at the NASA Langley Research Center in Hampton, Virginia.

On July 20, 1969, Neil Armstrong and Buzz Aldrin had entered the LunarModule they named 'Eagle' and were descending to the surface.

As planned, the software rebooted and reinitialized the computer, and then restarted selected programs at a point in their execution flow near where they had been when the restart Apollo 11, each time a 1201 or 1202 alarm appeared, the computer rebooted, restarted the important stuff, like steering the descent engine and occurred.

As Adler recounts in the Apollo Lunar Surface Journal, "On running the DSKY to let the crew know what was going on, but did not restart all the erroneously-scheduled rendezvous radar jobs.

For the Apollo lunar ascent and descent module single main engine and sixteen attitude control thrusters, the fuel and oxidizer were, respectively, hydrazine and nitrogen tetroxide.

In this image showing the Apollo 17 lunar ascent module "Challenger" supposedly lifting off from the Taurus-Littrow landing site there is no flame, exhaust, or even engine exhaust shroud visible from the bottom of the lunar ascent module.

When the sun is low in the moon's sky, vertical objects on the moon's surface, such as alleged standing astronauts and LM spacecraft walls, would have been nearly perpendicular to the sun's rays and would have been receiving nearly the full brunt of these rays.

Anyone with an interest in the moon or the phases of the moon -- for whatever reason -- should find some valuable information here, including a free current / daily moon phases website module, how to get a moon phases calendar software application, and other lunar phases information, including links.

The sun always illuminates the half of the moon facing the sun (except during lunar eclipses, when the moon passes thru the earth's shadow).

The second man to walk on the moon, Aldrin was the lunarmodule pilot on the Apollo 11 mission.

Many of the most famous photographs returned by the crew are those of Aldrin in the white Apollo space suit, mirrored space helmet reflecting Neil Armstrong who was the photographer for the first minutes on the moon.

He served as backup command module pilot for Apollo 8, before he becoming lunarmodule pilot on Apollo 11.

Astronaut Edwin E. Aldrin, Jr., lunarmodule pilot, walks on the surface of the Moon near a leg of the LunarModule during the Apollo 11 extravehicular activity (EVA).

While astronauts Armstrong and Aldrin descended in the LunarModule (LM) "Eagle" to explore the Sea of Tranquility region of the Moon, astronaut Michael Collins, command module pilot, remained with the Command and Service Modules (CSM) "Columbia" in lunar orbit.

The history of the LunarModule, specifications, interior, and exterior LM views, as well as information about the Lunar Rover are included along with many web links to specific Apollo missions.

A variety of on-line activities for students which were designed to test their knowledge and let them learn more about LunarModules, the Apollo Missions, and the Moon are available in the For Student section.
